软土流变特性试验及流变模型

Tests on Rheological Behavior of Soft Soil and Rheologic Model

摘要: 本文通过对上海软粘土流变特性的试验研究,在总结前人工作的基础上提出了一个带双屈服面的流变模型。该模型能反映土体的弹性、粘弹性、粘塑性性质,亦能体现土体的剪胀、剪缩特性,具有较为广阔的适用范围。

Abstract: From tests on Shanghai soft soil and predecessors’ works a double yield surface rheologic model has been introduced. It reflects visco-elasto-plastic behaviors, dilatation and shrinkage of soft soil. It has wide application in soft clay engineering.
